To all whom` it 'may concern.'

Be it known that l, WILLIAM GOLDIE, a resident of Willrinsburg, in the county of A|legheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Hoops, and l do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to metallic hoops for barrels, casks, kegs, tubs, and the like. Its object is to provide a hoop which can be made from ver thin sheet metal and which will provide a road surface for driving and at the same time be properly trussed to give strength to the hoop and to thi barrel to sustain loads. It has particular reference to hoops for barrels for containing1 dry material, such as flour, lime, etc., in vwhich it is important to provide a. hoop very light in weight and cheap and yet sufficiently stiff to sustain the blows in drivin and of sufficient truss strength to hold t ic bari-cl to shape; though of course it may br employed to advantage with heavier hoops tor barrels containing li uids.

o these ends itroosisis. generally stated, in the hoop composed ot' :i mrt-.diie strip hav ing at its up er or driving` edge an outwardly projecting4 ange and .drow the saine an inwardly projecting lip i. onnertcd thereto by a creo-se, making a Vslm.prd or reverse open fold, this flange and lip providing a broad surface for engagement with the inaul or driving tool and adapted to he closed down in the course of the driving of the hoop to place, closed i or trussed member extending around the barrel and also giving stillness to the hoop to withstand outward or bursting strain. It also consists in certain other improvements hereinafter rcterrrd to.

In the accom anying drawing Figure l is a view of tht` preiiirrcd forni ot' hoop; Fig. 2 is a side view partly brolaen irony, part of the view showing thc hoop applied to the chinu` portion thereof; Fig. 3 is a likview showing the hoop a i )lied to thebilge portion of th(` barrel; am ig. 4 is a cross section showing the 'oint between the ends of the hoop 'llie hoop is preferably inadc troni wry thin shoot metal. sur-h as 2R to itl-gage. whirh ran be out to proper wid-th and tlm ii-snltin;

strips fed to propri' bonding nini hinory 1o i shape thorn The hoop has the bedr portion 2 and the upporrib 3 and tho loner rib l.

so providing an outwardly projecting i io r These ribs are preferably formed alike so that thc hoop can be passed over thc barrel either way, and the saine description will ap'ily to both ribs. The rib has the outwardly extending flange 5 and beyond the saine the in wardly extending lip 6, these two being con nccted together by an actual crease or bend 7, as distinguished from a` mere curve, and giving a V-shaped or' reverse open fold, the crease forming the line for the foldingr of the flange and lip together, so forming an o en fold which under the blows of the mau or driving tool is forced together and forms a practically closed fold as shown. It is preerred that the outwardl and inwardly ex tending portions of the r1b shall be about of the same width as illustrated. When the hoop as so constructed is a plied to the barrel the o en fold provides a )road surface to receive tlie driving blows upon the top edge of the same, and said blows will tend to close down this open fold, bringing the lip (5 down into Contact with the flange 5 and so forming a practically closed fold as illustrated in Figs. 2 and 3. This results in an out wardly extending closed ribextending around `the upper edge of the hoop as driven and which is stiff and stronir enough to protect the edge of the barrel while at t ie same time it gives reat strength to resist bursting strain and fives great truss strength to hold the barrel to shape. The construction may be employed either as a chime hoop or as a bilge hoop, the latte-r being shown iu Fig. 3, and where it is evident that the reverse flange 3 l provides a broad surface for the 0nd ol the driver, and the blows of the salue in drivinfr down solid around the barrel will l the hoo practica ly closet up the open fold and bring i the hoop to about the form illustratori. The other, or lower, edge 4 of the hoop as driven on the barrel forms a strengthening trusscd ribextendingaround l hc barrel, and in its open torni also strengthens the hoo to sustain I bursting strain and `stiflrns am trusses the i same, both edges of thi` hoop imparting to it l ri-eat truss strength and sulliricnt load rarry i nig strength wher-eth0 barrels resting on their bilge portion are piled one upon thc other. t The hoop is exceedingly snnpie in roul struction, requiringr no roinplil ated machini cry in its nnunll'artnro. lr no he inadc of wry thin short nieto! and tlwroforr wij: rhrap and yet pro\A ide; :i .slitiirnnlljr braaf lain-tarro l'or drivingr to ploro. and nlzfr. in i phur giros n strong, still'. truest-f! hor-i :fil i llt) hy the foldiney over ol its edges liability to the euttingolthehund ofthe workmaninhandling the hex-rel ie overcome. While I prefer to employY the open folded rih et each ed e, it is i evident that! it may he formed et the driving edge only.

What I oleixn is;

l. A metallic hoop for barrels formed of a motel strip having e concentric upper or driving edge formed of' en outwardly extend ing V-shnped reverse open fold.

2. A metallic hoop for herrels formed of a [metal strip having concentric u per and lower ed es, the up er driving e ge hein formed o en outwar( ly extending V-shupe 15 reversible fold and the lower edge being of' like form.

In testimony whereof, I the said WILLIAM GoLmE have hereunto set my hand.
